Embodiment
A kind of anti-backfire gas-cooker of the present utility model is described in detail below with reference to Figure of description.
As shown in figure 1, a kind of anti-backfire gas-cooker includes housing 1, burner 2, described stove are provided with described housing 1
First 2 are connected by anti backfire valve 9 with source of the gas, the switch 6 with control source of the gas break-make are provided with described housing 1, described opens
6 are closed with electrical control gear 5 to be connected.Fiery disk 3 and fire cover 4 are provided with described burner 2.
As shown in Figure 3 and Figure 5, described anti backfire valve 9 includes valve chest 92, and it is logical that one is provided with described valve chest 92
Hole, described through hole be divided into from front to back first paragraph through hole and second segment through hole (using combustion gas flow to the direction of burner 2 as
Before), and the diameter of the first paragraph through hole is more than the diameter of the second segment through hole.In described first paragraph through hole from front to back
It is disposed with regulation fixed block 93, spring 94 and spheroid 91.Described regulation fixed block 93 passes through screw thread and described valve casing
